Computer fried and lost the application.

Hi there, @LOX.

Thanks for reaching out to the QuickBooks Community. How are you doing today? I hope all is well. 

To clarify, are you asking if you can move your QuickBooks Desktop company file, which resides in a zip file, and migrate it to QuickBooks Online? If so, you can do this. First, you'll need to extract the .qbw file from the zip archive. Then, you can either open the .qbw file directly in QuickBooks Desktop or restore it as a backup copy. 

You'll need to ensure that you're subscribed to QuickBooks Online. Please note that you have 90 days from the time you create your QuickBooks Online account to move your data.

Once you're subscribed to Online, you have two options to migrate. You can use the migration tool that's built right into QuickBooks Desktop, or you can use the online migration tool. Since your company file resides in a zip file, I recommend using the Desktop version. This way, you can review your company file and ensure there is no missing data. 

Here's how: 

1. Sign in as an admin in QuickBooks Desktop.
2. Export your QuickBooks Desktop company
   1. In QuickBooks Desktop Pro and Premier, go to Company, then select Export Your Company File to QuickBooks Online.
   2. In QuickBooks Desktop Enterprise, press CTR + 1 to open the Product information window. Then press CTRL + B + Q, then hit OK.
3. Click on Get started.
4. You’ll see the “Let’s bring your data to QuickBooks Online” screen. Select how you want to move your data:
   1. Bring all of your company data.
   2. Bring only lists and balances. (This is helpful if you have a large file and don’t want to bring over every individual transaction.)
5. If you have inventory, you can:
   1. Tap on Yes, track inventory using FIFO, then select a starting date.
   2. Select No, don’t move inventory. You can move your inventory manually later.
6. If you use multi-currency in QuickBooks Desktop, you’ll have to select a home currency.
7. You will be asked if you have a QuickBooks Online account.
   1. If you do, select Yes, sign me in, then hit Continue.
      Note: This is the account you created when you purchased QuickBooks Online in Step 1.
   2. If you haven't signed up for QuickBooks Online, you can select No, I need to create one. This'll create a QuickBooks Online Advanced trial company. We recommend you go to QuickBooks.Intuit.com/accounting to buy the right QuickBooks Online offering for your company before you move your data.
8. Sign in with your user ID and password you set up for your QuickBooks Online subscription.
9. You’ll see your QuickBooks Online company names and subscriptions listed. Choose the company you want to move your data to.
10. Click on Continue, then select Export. You'll see a progression bar as your data is moved over to QuickBooks Online.
    Note: If you already have data in a QuickBooks Online account, QuickBooks will ask if you want to replace the existing data.
    • Hit Agree, then Replace.
    • Tap on Yes, go ahead and replace the data, then select Replace.

For additional information about this process, I'm including some help guides below.
